Abstract

We re-evaluated the surface roughness of Europa at scales between 30 m and 5 km using stereo-pair images collected by the Solid State Imager (SSI) aboard the Galileo mission with a resolution between 9 m and 255 m per pixel. These images have been adjusted relative to each other to obtain consistent mosaics used for geomorphological mapping. Overall we have a set of nine regions covered by stereo images. The roughness is derived for different geologic terrains which have been distinguished by geomorphological mapping and analyzed separately. For each facies studied, we report the structure function, the breakpoints, and the respective power laws parameterized in terms of Hurst exponents. We also discuss the implications for laser and radar performance as well as for a potential lander.
